It's fun when you include the whole quote:
"The distance from the headspacing step in the chamber and the beginning of the rifling is shorter in CZs than most (not all) pistols. This means that some ammo, depending on profile, might not fully chamber and will jam the bullet into the rifling, which increases pressure unnecessarily and is not a good idea with stout-loaded defense rounds, or it will outright hold the pistol out of battery and render it useless. This worst case scenario is not a common scenario, and most quality JHP defense ammo will work in a CZ just fine. ALL of your commercial round nose FMJ plinking and target ammo will work just fine."
There are also people in that very thread that mention not having issues, and describe the issues as being more common with longer 147 gr bullets or truncated cones, such as on a defensive JHP. That's not what the OP is shooting.
